Haven't had the 63 out for two weeks and started making a grinding noise. It was there one day adn gone next. Did a little investigating and couldn't locate were it was coming from. Took it out again and new something was up. Jacked the front up and started pulling stuff off. Didn't take long to find the problem. Looks like a bearing went out on the drivers spindle OR I didn't do my part on assembly. This will be the third season since doing the 78/79 spindle conversion without issues. Not sure if I can repair it yet, looks pretty bad on the bottom side metal ground into metal.

Does anyone know were replacement spindles can be found? I was lucky 7yrs ago to find a donor tbird for the parts knowing i could use them.

Thanks for any suggestions or ideas.

Central Illinois.

Taking a closer look and wondering how these were machined? The bottom of the tapered shaft has some damage. The machined part that is furthest inside and not tapered is good, no damage. the small machined diameter furthest out doesn't look the best some metal to metal damage.

Does anyone think I might be able to "buff" the surfaces just trying to smooth it out? Going to pick up a new set of inner/outer bearings and put in rotor. Trying to visualize how this functions on the tapered part of the spindle shaft.

Thanks

Over the years I have saved quite a few damaged spindles by filing the damage smooth and buffing with emory cloth. The tapered part of the spindle is not very important but any sharp edges should be filed off to be smooth so as not to cause a stress riser which could lead to the spindle breaking at that point. If the spindle has a lot of blue from getting hot the spindle should be replaced. The new bearing needs to slide freely on and off the spindle. The important thing is that when your tap the new bearing races into the rotor that they seat snuggly and do not spin freely in the bore. If they are loose you do need to replace the rotor.

Just wanted to give an update:

Seems like the guy who put this back togeather (me) had installed the nuts on to tight :( After asking and doing some reading I have to assume since this was a body off restoration and put back togeather by me alot was done from memory and not consulting a manual. Stopped by the neighbor/mechanic for some advice and he showed be how to properly check and install. Glad hes down the road!

I was able to polish the outer wheel bearing surface, was not as bad as i thought, but did require a little elbow work. To admit how much of a novice I am, I ordered a new rotor thinking mine was trashed....nope didn't realize i could replace the race's when i purchased the new bearings.
Always learning,
Kevin
